Increasing the height and width of the slick slide. How to avoid jarring slides?

Question

css

When scrolling the carousel (especially to the right side), the slides twitch. How to fix (at least in what direction to move)? Already got to perversions with settimeouts, tried to change the scale, instead of the height and width (at best, the slide twitches after passing a full circle).

PS You cannot increase the distance between blocks.

Answer 1

The original size of the slider images must be the same
